Protein binding partners of SCAF8 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SCAF8 as an antibody target. Whether an autoantibody or antibody against SCAF8 could matter depends on whether native SCAF8 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SCAF8 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label SCAF8 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
